Yay! After several days of tedious work, inaneworld is now running on it's new server. It was running on windows 2003 with IIS. Now, it's running on Ubuntu with Apache. I used the turnkeylinux.com "wordpress" appliance. A word of caution: watch the memory usage. Docs say that you can run this with 256M of RAM (I'm running it under HyperV, but this probably applies whichever hypervisor you are using). I found that after I loaded all my dozens of plugins, the bloat caused the machine to become unusably slow (sometimes hang). I bumped the RAM to 400M and it lasted longer, but still hung. I bumped it again to 600M and now it seems happy. Please let me know what you think of the performance, especially if you notice a difference vs the old server.
Merry Christmas and Happy New Year!
